Twistors-Based Attitude-Orbit Integrated Control for Spacecraft: A High-Order Fully Actuated System Approach

In this article, the twistors modeling method and high-order fully actuated (HOFA) system approach are utilized to investigate the attitude and orbit integrated control problem of spacecraft. Initially, a first-order state-space model is formulated to represent the attitude and orbit dynamics of spacecraft. This model is subsequently transformed into a HOFA system model. Based on this transformed model, a control strategy is meticulously designed. With the developed control strategy, a linear closed-loop system is obtained, whose poles can be arbitrarily configured. The effectiveness of the proposed control strategy is ultimately verified through detailed simulation results.
